That worked. Thank you very much. Now I have disabled (greyed out) the
buttons for certain users. That's what I have looked for.

(Sorry I took so long, I was updating my system).

You want to disable only the buttons, or the functionality? For one
user, or several?

Assuming you want to disable the functionality for one user, this
disables both the functionality *AND* the buttons (they show up grayed
out):

$ cat /etc/polkit-1/rules.d/10-no-restart-shutdown.rules
polkit.addRule(function(action, subject) {
if (subject.user == "myuser") {
if (action.id.match("org.freedesktop.login1.power-off") ||
action.id.match("org.freedesktop.login1.reboot")) {
return polkit.Result.NO;
}
}
});

Of course, change "myuser" for the user you want to disable this. You
can also use groups (subject.isInGroup("group")), or use "suspend" or
"hibernate" instead of "reboot".

This works for any desktop that uses systemd (logind, technically) for
session tracking: AFAIK, this should work for at least GNOME, Xfce,
and KDE.

[gentoo-user] XFCE4: How cab I disable Restart and Shut down buttons?

2014-08-11 Thread Johannes Geiss 
Hello there,

I have XFCE4 and Systemd running and I want to know if it is possible
to disable or remove the buttons "Restart" and "Shut down" at the
logout dialog (xfce4-session-logout).

If so, how?

Thanks for any information.

Bye
Johannes
